Auto Ground Balance Procedure
The metal detector ground balance has to be done on ground free of any metals; otherwise, the ground
balance will be incorrect if done while a metal is present. This will generate undesirable false signals.
Procedure:
1. Lower the search coil approximately 1 inch above the ground and keep it parallel to the ground
surface.
2. Press and hold the ground balance button. While holding the ground balance button, raise the coil 4-5
inches above the ground while keeping the coil parallel to the ground, and release the ground balance
button.
3. To verify if the metal detector is properly ground balanced, move the coil up and down several times
to verify if there are any false signals. If the metal detector is still noisy while searching, there can be 2
reasons.
3a. The ground balance is done incorrectly and the process has to be repeated starting from step 1.
3b. The ground mineralization is high and the sensitivity has to be reduced by 1 or 2.
